Identify the nets which can be folded to form a cube (cut out copies of the nets and try it)

Dice are cubes with dots on each face. Opposite faces of a die always have a total of seven dots on them.

Here are two nets to make dice (cubes); the numbers inserted in each square indicate the number of dots in that box. Insert suitable numbers in the blanks, remembering that the number on the opposite faces should total to 7.

Can any of the following be a net for a die? If no, explain your answer.

The dimensions of a cuboid are 5 cm, 3 cm, and 2 cm. Draw three different isometric sketches of this cuboid with height (i) 2 cm (ii) 3 cm (iii) 5 cm

7. Give (i) an oblique sketch (ii) an isometric sketch for each of the following: (a) A cube is with an edge 4 cm long. (b) A cuboid of length 6 cm, breadth 4 cm, and height 3 cm.
